When to plant

Plant during your local cool growing season. In colder regions, use spring or late-summer/fall sowings and allow enough growing time before hard freezes.

How to plant

1. Prepare loose, well-drained soil or a clean seed-starting mix. Start in a protected tray in spring.
2. Surface sow and press in; light is needed. Keep the seedbed evenly moist until seedlings emerge. Then water when the soil needs it, allowing excess water to drain.
3. Thin or transplant to the listed final spacing. Give seedlings sufficient light and check moisture as roots establish.

How to harvest

Pick a few young leaves without stripping the plant. Remove unwanted seed heads and control spreading roots.
